- To all whom 'it may concern;

Be it known that I, SAMUEL B. Moscovirz, a citizen of the United States, and a resident of the city of New York, county of New York, State of N ew York, have invented certain Ynew and useful Improvements in Exhibiting Apparatus, of which the following is a specification.

The invention relates broadly to exhibiting apparatus, and more particularly to suchapparatus in which an exhibiting device is moved intermittently to exhibit or remove an indication, which indication may be of any nature conveying an idea, as, forinstance, the name or number of a station.

An object of the invention is to effect the exhibit of the indication economically, and, more particularly, to provide in an electric motor driven apparatus, means whereby stored energy of momentum alone effects a movement of the exhibiting device, instead of being wastefully dissipated, as heretofore.

In the present embodiment, an exhibiting device in the form of a strip bearing indications is arranged intermittently to be shifted through measured distances across a sight opening or window. rlhe shifting is accomplished by an electric motor for the source of mechanical power. Automatic means is rovided for holding the motor circuit closed or a certain period and for breaking it before the strip has been shifted the complete measured distance. A suitably formed cam disk and follower is comprised in this automatic means. v

A further object of the Yinvention is to combine automatic means with the apparatus whereby the exhibiting strip may be brought to a positive stop upon being shifted the complete measured distance.

Still a further object is to provide for the shifting of the strip both in a forward and a backward direction by a reversible electric motor while providing for the automatic' control of the motor circuit.l namely, being held. closed and being opened previous to complete shifting of the strip, independently of the direction of rotationof the motor.

- Further objects of the invention will be pointed out in the accompanying claims and will be apparent from the following description and accompanying drawings. In the indicating strip in one direction and also an apparatus capable in itself of feeding the indicating strip vin either of two directions. I In the drawings, which form part of this application, like reference characters designate corresponding parts.

is a plan view of the apparatus within the` Fig.-

casing, and shown at the left of Fig. 1. 5 is a front elevation of a modified window plate construction. Fig. 6' is a diagram showing the circuit connections ofthe motor, starting magnet, &c. Fig. 7 is a fragmentary elevation of a modification of the apparatus shown at the left of Fig. l. Fig. 8 is a diagram showing the circuit connections for the modification shown in Fig. 7. Fig. 9 is a front elevation ofthe apparatus. Fig. 10 is a fragmentary cross section through the shaft 16 of F ig.'7 showing the cams and follower parts.

Referring now more indetail to the` drawings :Ml indicates a suitable casing for the apparatus, in which is mounted a suitable motor 2 illustrated in the form of an electric motor. 3 denotes a suitable Supporting frame mounted on the casing 1, and for the Apurpose of supporting the driving mechanism, &c. 4 denotes thedriving shaft of the motr 2 and has fixed to its free end the driving pinion 5 which meshes with the gear 6 carried on the shaft 7 rotatably mounted in the frame 3 and lying parallel to the motor shaft 4t. The pinion 8 is xed to the shaft 9 which is rotatably mounted at the rear of the frame'3 and carries the fly governor l0 which serves to control the speed of the electric motor.

Upon a central shaft l1, rotatably mounted in the frame 8, is fixed a gear 12 which is in mesh with and is driven by the pinion 13 fixed to the shaft 7, which, as has been described, also has fixed thereto the gear 6.

Shaft 11 also has fixed thereto a pinion 14 that meshes with a gear l5 carried by the shaft 16 which is rotatably mounted in the forward part of the frame 3. Through this drawings there is illustrated both an appal train of gears 5, 6, 13, 12, the lshaft 11 is di- 'ratus capable of progressively feeding an l rectly connected to the motor, and by the same train of gears and, in addition thereto, by the gears 14 and 15, the shaft 16 is directly vconnected to the motor.l

. The central shaftfll is extended out bea the frame 3 and longitudinally of the casing 1, and carries the feeding roller 17 fixed thereto (see Figs. 1 and 2). This vroller lies beneath-` a superposed parallel roller 18 between which is threaded the indicating strip 19. The surface of the roller 17 (see Fig. 2) is' so formed as to engage the exhibiting strip 19 in a manner capable of imparting movement thereto. This may be accomplished in any suitable manner, one instance of which is the providing of the roller 17 with a friction surface, as would be the case if the roller were made of rubber. .It is to be understood, however, that any suitable means for causing the feeding roll 17 to move the strip 19 is contemplated. In the apparatus illustrated the roller 18 engages the opposite side of the indicating strip 19 from that engaged by the roller 17 and the reaction between the two rollers serves to provide a tight gripping action for the roller 17 against the indicating strip.

' One end .of the indicating strip may be secured to the winding roll 20, and the other end of the exhibiting strip, after passing over the guide rolls 201--201 and before the -transparent window 21, may be secured to the winding roll 22. Suitable power trans'- mission means, which is shown in the form of a belt 23, belted from the roll 17 to the winding roll 22, is provided. Suitable ower transmission means for the winding roll 20 is also provided and is illustrated in the form of a belt 23 passing from the winding roll 22 to the winding roll20. As illusltrated in Fig. 2, the winding roll 22 has a tendency to wind up the exhibiting strip, while 2O unwinds lit by reason of the belts 23 and 231 connecting these rolls to shaft 11. As indicated, the power transmission means for winding the rolls permits of acertain amount of slippage, which will in'a measure compensate for the varying diameter of the exhibiting strip wound up on the winding rolls. The consequences of the varying diameter of the strip wound on the winding rolls may be compensated for in other ways well known in the art, the present embodiment being for purposes of illustration merely. It is to be understood, however, that the exhibiting strip is caused to be moved a measured distance b a feeding means, as the roll 17. Obvious y, the measured distance which the exhibiting stri is caused to be moved is dependent, there ore,

upon the number of rotationsimparted to l fixed to the shaft 16 previously described as being driven by the pinion 14 meshing with the gear 15, which pinion and gear may be suitably proportioned so that for one rota-l tion of the disk 24 the desired number of rol tations of the feeding roll 17 required for feeding the exhibiting strip the measured distance may be secured. Figs. 1, 3, 4 and 6 show the parts coperating with the disk 24 in normal positions. Formed by cutting out a portion of the periphery of the disk 24 is a cam surface 351 which terminates in a radial shoulder 3511. As shown in Figs. 3 and 4, a follower or pin 26 engages the periphery of the disk 24 and is shown located against the shoulder 3511. This follower 26 is carried at'the end of an arm 25, which is pivoted at.its rear by the spindle 27 in the framev 3. The spindle 27 is rigidly secured to the arm 25 and there is also secured to the spindle 27 an extension arm from the armature 30 which is in operative relation to the starting magnet 29 carried on the bracket 28. Fixed to and extending out from the spindle 27 is a resilient contact arm 31. Carried by the frame 3 andinsulated therefrom is a coperating contact arm 32, which may be adjusted relatively to the arm 31 by means of the screw 33, which is likewise insulated from the frame 3.

A suitable traveling circuit closer 34 may be provided and this may be embodied as illustrated in Fig. 6 when the apparatus is to be used as a station indicator for cars or trains. In this instance a stationary block in any suitable form, such' as that indicated at 3311 in Fig. 6, is provided so that the circuit closer 34 carried by the car indicated by 35 will contact with the block 33 and close the circuit indicated connecting the battery 341 with the actuating magnet 29. The circuit closer 34 closes the circuit through and energizes the magnet 29 for armature 30 to be attracted. The attraction of the armature 30 will cause the spindle 27 to rotate and elevate the arm 25, which car ries the pin 26 clear of the shoulder 3511 and causes the contact arm 31 to contact with the coperating contact arm 32. The parts 31-32 constitute a circuit closer for the operating circuit of motor 2, so that vwhen the parts 31 and 32 contact with one another, current flows from the battery 331 through the motor 2 to operate the same. As soon as th`e motor 2 starts moving the shoulder 3511 is caused to move beneath the. follower or in 26, so that upon the denerjust a sufficient period of time to cause the gization of t e magnet 29 the pin 26 will not although the circuit for the actuating magnet 29 has been broken. The motor 2 continues to operate until the disk 24 has been rotated sufficiently for the follower 26 to follow down the cam surface 351 a sutiicient amount to cause the arm 31 to break connection with the arm 32 and open the motor circuit. The exact moment of-breakingthe motor circuit within the limits of the cam face 351 may be determined by adjusting the l/vith the apparatus illustrated in Figs. 1'

to 4 and 6, inclusive, it will be necessary to duplicate some of the parts in order to cause the feeding of the exhibiting strip in a reverse direction. To make this two direction feeding possible and to simplify the apparatus necessary, l have devised a modification. of my mechanism as shown in Figs. 7 and 8, wherein two disks 36 and-361 are Xed to the shaft 16. The disk 36 vcorresponds in form to the disk 24. It also is positioned on shaft 16 in the same relative position as is disk 24. The disk 361 correspends in formto the disk 24 and disk 36. However it is positioned upon shaft 16 reversely to disk 36 so that its shoulder 51 faces oppositely relatively to the similar shoulder of disk 36. In this modification two arms 38 and 381 take theplace of the single arm 25 shown in F ig. 1. ins or followers respectively indicated by 52 and 53 are fixed on these' arms to engage the peripheries of the disks and 361. The arms 38 and 381 are loosely mounted upon the spindle 27 upon insulating bearings 39-391 and are independently movable upon the spindle 27. An extension arm 40 extends out from the spindle 27 andris provided With laterally extending members 41 and 411 forming a l`like construction which extends underthe arms 38 and 381,v so that When thearmature 30 is attracted by the magnet 29 to rotate the spindle 27, the members 41 and 411 serve to elevate the arms 38 and 381 and lift the followers 52 and 53 clear of the shoulder 51 and its companion formed in the disk 36. It

should be understood that the arms 38-381- are suitably insulated from vthe disks 36-361 and the member 40, which may be accomplished by forming the parts 41, 411, 52 and of insulation, as indicated. The contact piece 32 is present in this modification and likewise may be adjusted by the screw The arm 42 fixed to move with the arm 38, cooperates with the arm 32 and the circuit connection for the arm 42 is through the spring arm 43, which bears against the rear of the arm 38. In a similar manner the arm 421 is fixed to the arm 381 to cooperate with the contact 32, and the circuit@connection for the arm 421 is through' the spring arm 431 bearing uponl the arm 381.'y In this modi` tication a reversible motor 37 is provided, while the train of gears connecting with its shaft 4 through the spur gear 5 may be the' same-as that previously described in connection with Figs. 1 to 4 and 6, inclusive. The circuit for the magnet 29 may be similar to that illustrated in Fig. 6. The bat-' tery 331 furnishes power for driving the motor 37 and oneterminal is connected to the arm 32, as illustrated, while the other terminal leads directly to the armature ter.- minal 54 of the motor 37, the other armature terminal 55 is connected to the movable member of a two-point switch 45, the respective contacts of whicharc connected by wires 44 and 441 to the spring arms 43 and 431, which have previously been described being electrically connected to the contact arms 42 and 421. The field winding of the motor 37 is suitably connected to the reversing switch 46, as indicated, so that the direction of the current traversing the same from the battery 331 may be reversed in a manner `well known in the art, by the operation of the reversing switch 46.

vWhen the exhibiting strip is to be moved, the switches 45 and 46 are both shifted, say to the left-,in which case the circuit closing arm 42 is a live Contact, and the circuit closing arm 421- is dead. Upon the actuation of the electro magnet 29 to lift the armature 30, contact 42 is caused to connectwith contact 32 to close the motor circuit and start themotor in operation. The movement of the `armature-30 at the same time causes the members 41 and 411 to lift the pins 52 and 53 clear of the shoulders in the cam disks. The starting of the motor causes a rotation of both disks in'a direction to cause the shoulder of disk 36 to pass under the pin 52. Although the actuating magnet 29 is only momentarily energized', the periphery of the disk 36 in engaging against 'the pin 52 mainf tains the contact 42 in electrical connection with `the arm 32, although the arm 381 has been allowed to fall down again 'until its pin 53 engages the cam, portion 50. The motor circuit is, therefore. maintained by the contacts 42 and 32 until a complete rotation of the disk 36 has been nearly accompli'shednwhen, as has been heretofore described 1n connection with Figs. 1 to 4 and 6, inclusive, thel motor circuit is broken to allow the momentum of the parts to com- `upon the actuation of the magnet 29, but inl this'case the pin 53 by being raised clear of the shoulder 51 vpermits the rotation of the disk 361 in an opposite direction to that previously acompllshed. The motor circuit is cut oif before complete rotation is-accomplished, in a manner similar to that previously described for the disk 36 and they momentum completes the rotation.

It should be noted that when the apparatus has come to rest after movement in either direction, it is locked against move ment in both directions, the shoulder on the disk 36 vlockin against movement in one direction and te shoulder on the disk361 locking a inst movement in the other. On the other and, the construction is rendered capable of cutting of the power current before. a complete rotation in either direction and without otherwise increasing the number of parts described in connection with the first construction. The switches 45 and 46 may be operated in any well known manner -to suit the convenience of the work which the apparatus is to perform and they may -be located in any convenient position. If

` through the win ow 21. In this c ass of n the apparatus is used as a station indicator `for traveling cars,- it is obvious that the train contact 34 will operate in an automatic manner upon engaging suitable stops 33, and the desired indication would be caused to be dis layed by the ap aratus work thel switches 45 and 46 need be operated only upon the return trip of the car or` train. It is further to be understood that any desired number of the station/indicators described may be employed. Ap licants invention is directed more particu arly' to the automatic control of ower circuits for the individual motors drivlng the individual exhibiting strips.

In Fig. 5 there 1s shown a window 'plate construction comprising a frame 60 with ears 61 for attachment to the casing 1. A panel 21 ismounted in vframe 60 and mounted on the panel is an escutcheon plate 62 4which bears a suitable permanent\legend and provides an opening 63 which exposesl 19. This constructionv the indicating stri may be substitute Figs. 2, 3 and 9.
